Assembly Primer for Hackers Part 11 Functions Stack Tutorial

Static Dissassembly x86 101

This video demonstrates basics of x86 assembly language. It explains how a executable looks like in IDA. How the prologue, epilogue work, how to identify number of arguments to a function. Also it explains how to read assembly code and identify logic of the function and create C function based on the understanding. This video is supposed to be for new comers in the field of reverse engg. The goal is to teach people to identify code patterns in assembly.

Exploit Research Megaprimer Part 2 Memcpy Buffer Overflow

Bugs like buffer overflow, format string and use after free are often introduced by a wrong usage or bad coding practices. This talk will explain how to recognize and exploit them. It will also explain the security mechanisms developed and how to bypass them.

This course covers the exploitation of stack corruption vulnerabilities in the Windows environment. Stack overflows are programming flaws that often times allow an attacker to execute arbitrary code in the context of a vulnerable program. There are many nuances involved with exploiting these vulnerabilities in Windows. Window's exploit mitigations such as DEP, ASLR, SafeSEH, and SEHOP, makes leveraging these programming bugs more difficult, but not impossible. The course highlights the features and weaknesses of many the exploit mitigation techniques deployed in Windows operating systems. Al...

How to crack a program with OllyDbg [Serial fishing and selfkeygen]

Hey youtuber,
Today i'm going to show you how to crack a program again.
I'm showing you a lot of things this time I know
but i did serial fishing and selfkeygenning (a.k.a. autokeygen) before.

There are many nuances involved with exploiting these vulnerabilities in Windows. Window's exploit mitigations such as DEP, ASLR, SafeSEH, and SEHOP, makes leveraging these programming bugs more difficult, but not impossible. The course highlights the features and weaknesses of many the exploit mitigation techniques deployed in Windows operating systems. Also covered are labs that describe the process of finding bugs in Windows applications with mutation based fuzzing, and then developing exploits that target those bugs.
Topics covered in the labs for this class include:
* Exploiting a vanilla Windows stack overflow with no mitigations turned on
* Using WinDbg to analyze our crashes
* Removing bytes from your payload (such as nulls) which would prevent exploitation
* Finding functions to call by walking the Thread ExecutionBlock to find kernel32.dll's location in memory so we can call functions like LoadLibrary() and GetProcAddress()
* Hashing strings to use for comparison when searching for functions, in order to minimize the size of the payload
* Overwriting StructuredExceptionHandlers (SEH) as a means to bypass stack cookies (/GS compile option) and bypassing the SafeSEH mitigation
* Overwriting virtual function table function pointers in C++ code as another way around stack cookies
* Using Return Oriented Programming (ROP) to defeat Data Execution Prevention (DEP) aka non-executable (NX) stack
* Using libraries which opt out of Address Space Layout Randomization (ASLR) and SafeSEH to bypass these mitigations
* Using Python to mutationally fuzz the custom, never-before-analyzed, Corey's Crappy DocumentFormat and Crappy Document Reader in order to find and exploit the numerous bugs within
